Is my shin bone chipped or something?

Back in elementary school I was playing on the jungle gym and fell off a ladder and hit my leg on every rung as I fell. It hurt really bad and bruised and swelled up really bad. Soon after it happened we saw a doctor and she looked at it and said it would just "turn funny colors". Ever since then my leg hurts when I walk a lot or am on it too long or when I hit it off something. There is also an indent in my shin where the injury was that I don't have on my other leg. I think I chipped the bone or something cause if I didn't why would I still have pain now when I'm in high school for an injury I sustained in elementary school? Thanks =]
